Ceiling Fans Industry Glossary Description
This concise glossary serves as a clear, practical guide to the essential terms and definitions you will encounter in the ceiling fan industry, helping you navigate product specifications, technical documents, and industry discussions with confidence.
This reference compiles common jargon and key terms used in ceiling fan projects, acting as a quick dictionary to clarify technical concepts in reports, manuals, and engineering documents. Each entry includes simple explanations to aid understanding and application.
DC Fan
A fan equipped with a direct current motor. Compared to AC fans, they are typically quieter, more energy-efficient, and offer a wider range of speed settings.
AC Fan
A traditional fan using a standard alternating current motor. They are known for being simple, durable, and cost-effective, though they generally consume more power and have fewer speed options.
Dimmable LED
An LED light fixture that allows the user to adjust the brightness level. It is commonly used to create different moods and save energy.
Downrod
A metal rod that connects the ceiling fan to the ceiling bracket. Its length determines how low the fan hangs, which is essential for proper airflow in rooms with high ceilings.
Retractable Blades
Specially designed blades that retract above the motor when off and automatically expand via centrifugal force when turned on. Often used in fan lights for a minimalist aesthetic.
ABS Blade
Fan blades made of high-strength engineering plastic. They are moisture-resistant, durable, and can be molded into complex aerodynamic shapes for better airflow, commonly used in outdoor or modern fans.
CFM(Cubic Feet per Minute)
A measurement of the volume of air a fan moves per minute at its highest speed. A higher CFM indicates more powerful airflow and cooling performance.
RPM(Revolutions Per Minute)
The number of full rotations the fan blades make in one minute. It directly affects wind speed, though very high RPM may increase noise and power consumption.
HVLS (High Volume, Low Speed)
Refers to large industrial fans, typically over 7 feet in diameter. They move massive amounts of air at low speeds to provide large-scale circulation efficiently and quietly.
Blade Pitch
The angle of the blades relative to the horizontal plane. A steeper pitch generally allows for more airflow but requires a more powerful motor to overcome the increased resistance.
